A report of a louse sample identified as Colpocephalum cholibae Price & Beer by Oliveira et al. (2004), from the roadside hawk [Rupornis magnirostris (Gmelin)] in the state of São Paulo, Brazil, is regarded as a misidentification. A correction to the identity of the lice is given as Kurodaia (Kurodaia) fulvofasciata (Piaget). Key morphological differences between the genera Colpocephalum and Ku...

This article provides an overview of some perspectives about special issues in classroom mathematical teaching and learning that have stemmed from the huge explosion of research in children’s mathematical thinking stimulated by Piaget. It concentrates on issues that are particularly important for less-advanced learners and for those who might be having special difficulties in learning mathemati...

Re#ecting on Piaget's recently translated collection of sociological studies, we highlight some salient points in his approach to sociological issues. At the same time we attempt to explain the contrast between Piaget's singular in#uence in cognitive and developmental psychology with nothing comparable in empirical sociology. We believe that our own social research is a genuine continuation of ...

This text initially discusses the distribution of neurons in a neural network with non-supervised learning. A proposal for creation and destruction of neurons based on the activity related to the concepts being recognized is introduced. This model, called activity schema, is used to define a sensory-motor agent as a collection of activity schemata, each one representing a sensory-motor concept....

Jean Piaget was a master at observing the routine behaviors children produce as they go from knowing less to knowing more about at a task, and making inferences not only about how children understand the task at each point, but also about how they progress from one point to the next. This article examines a routine behavior that Piaget overlooked-the spontaneous gestures speakers produce as the...

BACKGROUND/PURPOSE It is common that intellectually gifted children (IQ ≥ 130) are referred to paediatric or child neuropsychiatry clinics for socio-emotional problems and/or school underachievement or maladjustment. Among them, those displaying developmental asynchrony - a heterogeneous developmental pattern reflected in a significant verbal-performance discrepancy (SVPD) on Wechsler's intelli...

entity) are represented at the cognitive level (a more abstract entity) during human development. Therefore, the importance of studying mathematical constructs inferred from behavior is due to the role that they may or may not play as common principles in the process of abstraction. Thus, the present analysis raises new questions for comparative studies within the theoretical framework proposed...

O presente artigo teve por objetivo analisar a importância do lúdico no processo ensino aprendizagem, através de jogos e brincadeiras na educação infantil. A pesquisa configura-se como bibliográfica tomando base autores Vygotsky (1984), Piaget (1972), Kishimoto (1994), entre outros. Os pesquisados apontam importante utilização qualidade oportunidades oferecidas à criança meio brinquedos garante...

Among empirical disciplines, computer science and the engineering fields share the distinction of creating their own subject matter, raising questions about the kinds of knowledge they engender. The authors argue that knowledge acquisition in computer science fits models as diverse as those proposed by Piaget and Lakatos. However, contrary to natural science, the knowledge acquired by computer ...

This paper discusses different approaches in cognitive science and artificial intelligence research from the perspective of radical constructivism, addressing especially their relation to the biologically based theories of von Uexküll, Piaget as well as Maturana and Varela. In particular recent work in ‘New AI’ and adaptive robotics on situated and embodied intelligence is examined, and we disc...
